Shows its reasoning
Each suggestion comes with an explanation. You see the data behind it — no black boxes.

§ 06 · The app
The app in use.
Dashboard
Today's workout, streak, recovery and progress on one card — no tabs, no digging.
Inside a workout
Sets, weights and RPE logged with one thumb. The rest timer starts itself — you focus on the lift.
Recovery map
A visual map tells you muscle by muscle when your body is ready for load and when it isn't.
Achievements
Your first 100 kg, best set of the year, streaks and milestones — kept in one ledger.
§ 07 · Features
Six things that work in the gym.
Log a set in 10 seconds
Set the weight, reps, move on. Big buttons, one-handed use, no ads between sets.
A plate calculator that knows
Choose the bar, weight, unit. Calculates plates per side, shows the nearest achievable load if the requested one doesn't divide evenly.
Recovery isn't guessed
History + subjective strain + progress. The app knows when to back off and when to push.
Works without a connection
Workouts load in advance. Gym basement, forest, aeroplane — it all works. Syncs when the network returns.
In Finnish, no translation glitches
Not "Bench Press — Level Intermediate". Real exercises, real terms, a language you can trust.
§ 08 · Getting started
Three steps. Then you train.
01
Tell your goal
Five minutes of onboarding. Experience, equipment, days, goal. That's it.
02
AI builds your program
A personal training block, no shortcuts. Every user's program is different.
03
Train, log, progress
The program adjusts every week to your data. You don't need to think about what's next.

§ 11 · Founder's note
This is where SisuLift came from
For years I built every program myself: RPEs, progressions, deloads. It all worked — but it took time, broke focus, and turned a simple thing into a needlessly complicated one.
SisuLift isn't a finished program. It's a system that tracks every set, understands your load, and suggests your next move. No rough outlines, no generic templates — just decisions based on what you actually do.
You stay in control. You accept, modify, or skip the suggestions. But you no longer have to start from scratch — or spend your time in Excel or a notebook.
Try it for 14 days free. No card, no commitment.
If it works, you keep going. If not, I want to know why — I read every reply myself.

Frequently asked, honestly.
Yes. You give no card details for the trial. If it's not for you, you put the app away, full stop. Billing only starts if you subscribe yourself.
It builds you a personal program based on your experience, equipment and goal. Reads your training history, adjusts the next week based on RPE and progress. You can ask it questions about your training in Finnish or English.
Especially for beginners. You don't need to know the terms, the program is chosen for you. Every exercise is instructed. The beginner program is designed so you learn the right technique first, then add load.
You can edit the program by hand any time. Swap exercises, loads, order. The AI learns from your changes and starts suggesting better next time. You're the boss.
Settings → Subscription → Cancel. One button. No chat support, no "why are you cancelling" surveys. You keep access through the end of your billing period.
Yes. When you open a workout online, it loads into memory. Gym basement, countryside, aeroplane — you log the sets and they sync when the network returns.
You can start fresh with SisuLift. There's no import from other apps — you most likely won't miss that old data once the program adapts to you in the first couple of weeks.
— Final word —
Your training deserves a better journal.
No commitment. No card. 14 days, and you decide yourself if it fits.
